This book accompanies an exhibition of the same names held at the Philadelphia Museum of Art upon the completion of onservation of Pontormo's famous portrait of Duke Alessandro de' Medici. Centering on Pontormo's painting and Angolo Bronzino's equally renowned depiction of another Medici duke, Cosimo I, the exhibition of some fifty sixteenth-century works from American and European collections explores the ways in which these artists changed the Renaissance portrait during this tumultuous period in Florence's history. In his catalogue entries, Carl Brandon Strehlke surveys the history and multifaceted significance of the Medici portraits and other paintings, drawings, coins, medals, books, and prints in the exhibition, offering a wealth of insights into the Medici dukes and the aritsts who served them. This fully illustrated volume also features Elizabeth Cropper's thought-provoking essay "Pontormo and Bronzino in Philadelphia: A Double Portrait," which explores the rich cultural and artistic background behind these artists' portraiture. The two Philadelphia portraits offer fascinating private views of important rulers of Renaissance Florence. An essay by Mark S. Tucker and colleagues discusses findings from the most recent conservation of Pontormo's portrait of Alessandro. A glossary, a geneaology of the Medici family, and a bibliography complete this publication. The book will accompany an exhibition to be held at the Philadelphia Museum of Art from November 20, 2004, to February 13, 2005.Strehlke, Carl Brandon is the author of 'Pontormo, Bronzino, and the Medici The Transformation of the Renaissance Portrait in Florence', published 2004 under ISBN 9780876331804 and ISBN 0876331800.
